Haemocomplettan® P During Elective Complex Cardiac Surgery
Efficacy and Safety of Haemocomplettan® P in Patients Experiencing Microvascular Bleeding While Undergoing Elective Complex Cardiac Surgery
Study Overview
Status
Intervention / Treatment
Detailed Description
Fibrinogen concentrate is increasingly used in surgical patients suffering excessive bleeding refractory to conventional hemostasis treatment. However, these studies published so far comprise small study groups with questionable study designs.
The aim of this study is to determine whether fibrinogen concentrate reduces blood loss and transfusion in patients undergoing elective complex cardiac surgery.
By choosing the domain of complex cardiac surgery which is prone for excessive blood loss and transfusion, we will focus on subjects undergoing high risk procedures. Hereby we hypothesize that administration of fibrinogen concentrate improves hemostasis in patients experiencing microvascular bleeding during complex cardiac surgery. This improvement of the hemostasis is measured by reduced blood loss and transfusion of blood products during surgery and the postoperative period.
Furthermore, we hypothesize that fibrinogen concentrate is safe and well tolerated in patients undergoing complex cardiac surgery. This hypothesis will be investigated by a detailed study of clinical outcomes.
Update regarding interim-analysis:
On 09 August 2013 an interim-analysis was performed as described in the protocol. The outcome was discussed during the Steering Committe of 09 October 2013. During that meeting, based on the results of the interim-analysis, the continuation of the current study was ordered.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Albumin
|
Human albumin with concentration 200g/L.
The study bottles of 50 mL will be diluted with saline and will contain 2g in total.
This concentration resembles the total protein load in the bottles with Haemocomplettan® P.

Dosing of study medication will be individually determined based on plasma fibrinogen concentrations (measured with Clauss method during the reperfusion period on CPB) and body weight.
Intravenous infusion within 10 minutes.
